CARBURETER.

Specification of Letters Patent.

Application filed August 30, 1912.

Patented llllar. 1t), 1914:. Serial No. 717,986.

2' '0 all whom it may concern:

Be it known that I, JOHN RUTHVEN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Carburetors, of which the following is a specification.

The present invention relates to improve ments in carbureters.

()ne object of the present invention is the provision of a carburetor in which any unnecessary moisture in the carbureted air is properly absorbed or filtered therefrom before the same is ready for delivery to the in tended apparatus, as for instance an explosive engine or a lighting system, there being provided an augmenting means, whereby a less volatile liquid, as alcohohmay be supplied within the carburetor for intermixing with the usual petrol or gasolene.

VViti the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings, Figure 1 is a vertical central sectional view of the complete carbureter. Fig. 2 is a detail side elevation of the air intake and back fire release valve taken at right angles to the showing thereof in Fig. 1.

Referring to the drawings, the numeral 18 designates a pipe which is connected at 19 to the cylindrical carbureter casing 20. The casing 20 is positioned upon a base 21, there being formed concentrically of the casing 20, a cylindrical tube 22, which provides a concentric flue vertically within the casing 20 with a partition as thereacross adjacent its upper end. Extending within the tube 22 from the lower end and to a point adjacent the under side of the partition 24, is a heating coil 25, which is fed from the radiator system of an explosive engine (not shown). The upper end of the tube 22 is sealed by the valve controlled disk 26, the valve 28 of which is held normally closed by means of the spring 27, the valve being opened by suction which is created by an explosive engine (not shown). The main disk valve 28 is provided with a port having a valve seat, upon which seats the pressure release valve The alves 2S and 29 are mounted so that the valve 28 will open by suction to admit air into the upper end of the tube 22, while the valve 29 opens in the opposite direction, due to the pressure within the tube 22, such pressure as for instance being caused by a back fire from the engine (not shown). This valve 25) is closed by the spring 29' and also allows for the escape of carburcted air should the pressure in the carbureter be above a predetermined pressure.

The tube 22 is provided with a plurality of perforations 30 through the wall thereof above the partition 2%, so that the suction created in the pipe 31 to the engine will cause air to be drawn through the valve controlled disl-I and by reason of the partition 2 1 acting as a deflector, the air will be drawn through the perforations 30 to the various chambers of the carburetor casing 20 as will presently appear.

A plurality of plates 32, each of w iich is provided with a vertically extending line 33, are disposed within the casing 20, and wire gauze supporting members or diaphragins 35 are disposed between each of the plates 32. The wire mesh diaphragms 35 are separated and disposed in pairs midway between the respective partitions or plates 32 and supported therebetween is a wiching 37. Each diaphragm 35 is composed of wire mesh or wire gauze.

In the upper end of the casing 20 is disposed the inlet funnel 38, whereby alcohol. may be poured into the upper end of the carburetor casing through the absorl'ient material 37 and the upper pair of gauze diaphragms 35 to the space 39, the evaporated alcohol being due to the suction of the air drawn into the apertures 30 by the explosive engine or other medium, through the superposed layers of absorbent material and the wicking, so that any surplus moisture will be absorbed therefrom so that by the time the carbureted air passes out of the delivery pipe 31, such carbureted air is practically dried. The pipe 31 is led directly to theexplosive engine (not shown) or to a storage tank (not shown).

The chamber 39 is provided with an alcohol drain cock a0 and an overflow pipe 5 the latter preventing the alcohol from flowing into flue 33, and thus commingling with the gasolene fed within said line and the delivery end 17 of the gasolene supply pipe. Thus gasolene is fed through the fine 33, and the absorbent material 37 arranged in the compartment as, and also the superposed gauze diaphragms disposed immediately below said compartment. The carbureted air will thus pass through the flue 33 of the second partition 32, it being drawn through the absorbent material and the various superposed diaphragms where the unnecessary moisture is extracted therefrom so that it is finally del'vered in the best possible state for combustion.

In order to permit the draining off of the gasolene from the lowermost level of the casing 20, a pipe 51 leads therefrom and may be directed back to the original supply tank (not shown).

hat is claimed is:

A carbureter, including an open base, a casing disposed thereupon and provided with a concentrically disposed cylindrical tubular chamber the full length thereof, a partition disposed within said tubular cham ber adjacent the upper end thereof, said chamber above the partition being provided with a. plurality of apertures therethrough in communication with the upper end of said casing, a valve controlled air inlet in the upper end of said chamber for controlling the supply of air to the chamber above the partition, plurality of partitions disposed within the casing about the tubular chamber and dividing the casing into a plurality of superposed and communicating compartments, each partition being provided with a short conduit projecting up ardly therefrom to a point below the center line of its respective compartment, a liquid hydrocarbon supply entering the upper compartment and concentric with the conduit of the upper partition, two spaced gauze diaphragms disposed within each compartment intermediate of the respective partitions, a carbureted air conducting pipe in communication with the lower compartment and adjacent the space between the gauze diaphragms thereof, the apertures of the tubular chamber being disposed adjacent to the space between the gauze diaphragms of the upper compartment, a packing of absorbent and filtering material disposed about the gauze diaphragms in each compartment, and means for supplying a less volatile liquid fuel disposed to direct such fuel into the space between the gauze diaphragms of the upper compartment.

2. A carbureter, including a base, a cylindrical casing disposed thereupon and provided with a concentrically disposed cylin drical chamber the full length thereof, the said chamber being open at both ends, a partition disposed within said cylindrical cham ber adjacent the upper end thereof, said chamber above the partition being provided with a plurality of apertures therethrough in communication with the upper end of the casing, a valve controlled inlet in the upper end of the cylindrical chamber for controlling the supply of to the same above the partition, a back pressure release valve also at tie upper end of the cylindrical chamber, a plurality of partitions disposed within the casing about the tubular chamber and dividing the casing into a plurality of superposed and communicating compartments, two spaced gauze diaphragms disposed within each compartment inter-mediate of the re spective partitions, a liquid hydrocarbon supply led to the upper compartment at the s race between two of the diaphragms, a carbureted air conducting pipe in communica tion with the lower compartment and adjacent the space between the gauze diaphragms thereof, the apertures of the cylindrical chamber being disposed adjacent the space between the gauze diaphragms of the upper compartment, and a packing of absorbent and filtering material disposed about the gauze diaphragms in each compartment.

In testimony that I claim the foregoing as m own, I have hereto afliXed my signature in the presence of two witnesses.
